The specific name is derived from the type locality (Dabashan = Daba Mountain); noun in apposition.	en	Cai, Yu-Jun, Wang, Lu-Yu, Zhu, Ben-Chao, Lu, Wei, Zhang, Zhi-Sheng (2025): Diversity of spiders in Daba Mountain National Nature Reserve, Chongqing, China (II): Two new species of Hahniidae (Arachnida, Araneae).

7AFD1EAC6471545EB5CAF04272235EAD.taxon	diagnosis	Diagnosis. The male palp of the new species is similar to that of H. corticicola Bösenberg & Strand, 1906 (Liu et al. 2015: 297, fig. 3 A – I) in the general shape of the cymbium, embolus, tegulum, and retrolateral tibial apophysis (RTA). It can be distinguished by the following combination of characters: a thorn-like process (TF) on the proximal femur (vs. absent); a flake-like patellar apophysis with a serrated margin (vs. rod-shaped with a hooked tip); and indistinct teeth on the distal retrolateral tibial apophysis (vs. distinct teeth) (Figs 1 A – C, 2 B – D).	en	Cai, Yu-Jun, Wang, Lu-Yu, Zhu, Ben-Chao, Lu, Wei, Zhang, Zhi-Sheng (2025): Diversity of spiders in Daba Mountain National Nature Reserve, Chongqing, China (II): Two new species of Hahniidae (Arachnida, Araneae).
